Gene-environment Interaction: The Causes of High Obesity Incidence.
نویسندگان
چکیده
Urbanization has provided experimental settings for testing the interactive relationship between genetic background and changes in lifestyle and dietary patterns. The concept of gene-environment interaction was described by epidemic of obesity along with urbanization. Genome-wide association has identified several genes such as melanocortin-4 receptor that associates with environmental influences of obesity. Gene environment (GxE) interaction refers to modification by an environmental factor of the effect of a genetic variant on a phenotypic trait. GxE interactions can serve to modulate the adverse effects of a risk allele, or can exacerbate the genotype-phenotype relationship and increase risk.

The Interaction between Dietary Fiber and the Mediterranean Dietary Pattern Score with FTO Gene Polymorphisms in Relation to Obesity Phenotypes
Introduction: Although variants in the FTO gene have been found to be associated with susceptibility to obesity, however, recent studies suggest that dietary intakes may modify the association. This study aimed to investigate the interaction of the Mediterranean dietary pattern (MD) and fiber intake with FTO gene polymorphisms in relation to obesity phenotypes. Materials and Methods: Participan...

Background and objectives: There is growing interest in assessing gene-environment interaction in the course of case-control studies. Difficulties related to the sampling of controls have led to the development of a range of non-traditional methods that do not require controls for estimating gene-environment interaction. One of these new modalities is the case-only approach, in which the asse...

Introduction: Obesity causes accumulation of proinflammatory factors in adipose tissue and it is regarded as a risk factor for diabetes and cardiovascular diseases. Aerobic exercise increases insulin sensitivityand reduces fat accumulation and proinflammatory factors. The present study aimed to investigate the effect of endurance exercise on resistin gene expression as one of the proinfammatory...

Rice bacterial blight caused by Xanthamonos oryzae pv. oryzae is one of the most destructive bacterial diseases of rice in some areas of rice cultivation in the world, especially in the tropics of Asia. The low efficiency of disease management methods, especially chemical methods, has led to more research on recognizing resistant cultivars and understanding resistance mechanisms through the stu...
